Be it known that 1, MICHAEL J. MoANENr,

A a citizen of the United States, residingat: Denver, in the county of Denver and State" of'fQolorado, have'invented a new and use-' fuljlmprovement in Water-Closet'Bowls, of

which the following is a specification,

a, My invention relates to an improvement inwater-closet bowls, and it is fully de- Wiscribed and explained; in the specification and illustrated inthe accompanying draw v the catch'14 tolthe condition illustrated.

ing,v,in which: i V a Figure 1 is a plan view of the bowl, and Figure 2 is a section on,line22, Fig. 1. The bowl 3, of any of the'usual general forms, is provided around its upper edge with a circumferential hollow rim 4 preferably closed about the bowl, except for a vent-opening shown to be provided at 5,

20 and opening at the rear of the bowl, into a chamber 6 at opposite sides of an inclined valve-seat 7 formed in its forward wall and upon which a flap-valve 8 is hinged for controlling the discharge of water into the bowl. A vented cylinder 9 extends through the top of the chamber 6 and contains a spring-pressed piston 10 having its pendent stem 11 connected at 12 by a link 12 with a lever 13 fulcrumed at one end to the rear wall of the chamber and extending at its opposite end to a catch 14 rising from the base of the seat 7 to be engaged, for releasably locking the valve, by a dog 15 pivoted on its rear face. The usual seat is represented at 16.

With the bowl in position for use, the flushing water enters the chamber 6 through a pipe 17, which may lead directly from the source of water-supply under any degree of pressure which may be the normal city pressure, or any pressure from one pound to a hundred pounds or more, per square inch, in which'case a suitable valve (not shown), but which should be springclosed, would be provided in the pipe in position relative to the seat 16 for convenient access for manipulation by the useror the pi e may lead from the more usuallyprovi ed valve-controlled rear or overhead flush-tank.

Admission of water through the pipe 17 fills the rim 4 and chamber 6, the combined reservoir-capacities of which need not, for the flushing purpose, exceed materially if at all, about two gallons of water. WVith the chamberfi filled, the resultant pressur of the water therein raises the piston 10 to tripfthefdog 15 and unlock the valve 8 to permit the co'n te nts .of the cliamb'erand rim to gush, into and flush'the bowl, whereupon the spring-pressure against the piston 10 restore's t-he"lever13 to .its normalposition for the dog-tripping purpose, and the valve 8"wjll' close by gravity against its seat and become locked by thedog '15 riding over Until" the "water-supply through the pipe 1.? "becomes arrested by closure of theafo're said valve controlling the same,there may be a more or less slight after-flow of water into the chamber 6 during its evacuation, depending on the time it takes for that valve to close; but the quantity of such after-flow should be negligible in the way of increasing the amount of actual flushing water from the reservoir afforded by the rim 4 and chamber 6.

The bowl-construction thus described renders it economical in flushing water and the comparatively small amount thereof is thoroughly effective owing to the pressure at which it discharges into the bowl. Moreover, the operation is wholly independent of any degree of'pressure at which the flushing-water enters the chamber 6, the mechanism being devoid of need of adjustment for adapting it to any degree of watersupply pressure; and the provision of the rear or overhead flush-tank being unnecessary, though ifalready installed the bowl may co-operate therewith, it may be dispensed with the resultant advantage of sav-' ing in space and equipment.

I realize that considerable variation is possible in the details of construction herein shown and described, and I do not intend to limit my invention thereto except as pointed out in the appended claims, in which it is'my invention to claim all the novelty inherent in the invention as broadly as permissible by the state of the art.

I claim:

1. A water-closet bowl having its back formed with a flush-water receiving reservoir-chamber discharging directly into the bowl through a valved opening and provided with means of communication with a source of flush-water supply, a valve for said discharge opening, and means actuated by pressure of water in, the reservoir, chamber for opening said valve.

2. A. water-closet bowl having its back formed with a flush-water receiving reservoir-chamber discharging through an opening' therein directly into the bowl and provided with means of communication with a source of flush-water supply, a self-closing valve seating against said discharge: opening, a hollow rim surrounding the bowl, said rim communicating at its ends with said reservoir-chamber and forming a supplemental extension of the reservoir, and means for locking the valve in closed position releasable by the pressure in said chamber of flush-water introduced therein.

3. A water-closet bowl provided with a rear flush-water receiving-chamber and a.

hollow circumferential rim in open communication with'each other and forminga reservoir, a self-closing valve seating at the discharge-opening in a wall of said chamber between the points of communication therewith of said rim, a locking device forreleasably securing the valve in its closedposition, and piston-operated means for unlocking said device by pressure against the piston ofwater" introduced" into said chamber for the flushing purpose.

4;. A water-closet bowl provided with a rear flush water receiving-chamber and a hollow circumferential rim in open communication with each other and forming a reservoir, a self-closing hinged valve seating at a discharge-opening in the forward wall of said chamber between the points of communication therewith of said rim, a catch on the valve-seat and a dog on the valve releasably engaging the catch, a lever f-ulcrumed at: one end in said chamber and extending at its opposite end, to a notch in said catch for-disengaging the dog therefrom, and a spring-pressedpistonfdevice extending intothe'chamber and having. a link connection-with the lever, for operating it todisengage the dog and unlock the valve by pressure against the. piston ofi water introduced into said chamber for the flushing purpose.
